DEVICE FOUR SHARPENING RAZORS.

SPECIFICATION forming part of Letters Patent No. 529,320, dated November13, 1894.

Application filed October 23, 1888. Renewed October 4, 1894x ISeria1No.524,927. (No model.)

To @ZZ whom, it may concern,.- l

Be it known that I, PETER JOHN CAESAE, manufacturer, a citizen of theUnited States, and a resident of Fergus Falls, in the county of OtterTail and Slate of Minnesota, have invented certain new and usefulImprovements in Devices for Sharpening Razors, of which the following isa specilication.

This invention relates particularly to imxo provements in devicesdesigned to be used in sharpening razors, knives, or similar articles,and the object I have in view is to provide a device by which anyperson, no matter how unskillful he may be, may quickly and properlysharpen the razor orknife; and the invention consists generally in theconstruction and combination hereinafter described and particularlypointed out in the claims.

In the accompanying drawings forming a zo part of this specification,Figure 1 is a perspective View of my devices. Fig. 2 is a plan of thedevice, the upper part being removed. Fig. 3 is a section on the'line -xof Fig. 2. Fig. 4 is a transverse section through the tool holder.

The present invention is an improvement upon that shown and described inmy Patent N0. 382,027, granted May 8, 1888.

In the drawings, 3 represents the handle of 3o my device which may be ofany suitable size and shape and formed of any suitable material. Theupper part of the handle, is preferably provided with a longitudinalslot 'as shown in Figs. 1 and 4, through which the blade of the razor tobe sharpened is inserted.

The handle is of sufficient size to contain the handle of the razorbeing sharpened, and to permit it to turn therein as the blade isreversed in the act of sharpening.

8 represents the frame formed preferably of the oppositely arranged rods7, which are joined together at one end by a block 10 forming apart ofthe frame 8, and at the other end by the blocks 13 and 15, also formingparts of said frame. This frame 8 is pivoted at 9 in the handle 3, so asto have lateral play therein, as the device is moved back and forth overthe strop 22, andit is provided with friction rollers 11 journaled onthe rods 7. These 5o rollers are important, because they run along astrop and actuate the reversing connections,

and through them the reversible holder. These rollers avoid unnecessaryfriction between the strop and reversing connections.

17 represents the razor holder, which is ceu- 55 trally journaled in theframe 8, on its longitudinal axis, having bearing at one end in theblock 10 and at its other end inthe blocks 13 and 15. rlhis holder, fora Aportion of its length, is of tubular form and is formed with 6o aslot 18 through which the edge of the razor projects. Rigidly secured onthe holder 17, is a pinion 19 which meshes in a rack 21 on thedownwardly projecting portion on one end of a frame 23, which is securedat its other end to the handle 3. By this construction, as the framecarrying the holder is moved back and forth over the strop, the holderis rotated in either direction, by the pinion engaging the rack. To aidthepinion 7o and rack in reversing the blade of the razor,

I locate in connection with the vibrating parts and within the handle, areversely acting spring 27 which, as the frame is moved to one side,returns the said frame and holder to normal central position withrelation to the handle.

I have shown a spring of substantially U- shape, and it is arrangedwithin the handle by being attached to the pivoted block 10 and 8orendered reversely acting by its forwardly projecting spring arms whichbear against the sides of the handle so that the spring is deiiected byany movement of the frame in either direction.

The manner of using the device is as follower-A razor or knife isinserted into the tubular portion of the holder 17 with its edgeprojecting through the slot 18 as shown in Fig. 4. The frame is thenplaced uponastrap- 9o ping surface which may be either an ordinary strop22, as indicated in Fig. 4, or any other suitable device. The operatorthen moves the device rapidly back and forth over the strop holding itby the handle 3. The friction between the frame 8 and the strop issufficient to cause the frame to turn upon its pivot 9 and swing in adirection opposite that in which the handle is being moved as far as theopening in the handle will permit. rIfhe roo pinion 19 is thereby movedover the rack-bar 2l and the holder 17 is turned upon its axis bringingthe edge of the blade in proper position upon the strop as shownin Fig.4. As soon as the movement of the handle ceases the spring 27 returnsthe frame to its normal position and the holder 17 is thereby turnedupon its axis, bringing the edge of the razor away from the strop. Themovement of the handle being now reversed the other side of the bladewill be brought against the strop and the operation reversed. The devicemay be moved back and forth over the strop as many times as may benecessary to bring the razor to the desired edge, and as rapidly asdesired, without danger of the edge nicking the sharpening surface.

Having thus described inyinvention, what I claim as new therein, anddesire to secure by Letters Patent, is-

1. In a razor sharpening device, the combination of an automaticallyreversing razor holder, a handle, means for engaging a st rop foroperating the holder, and a spring acting on the holder, substantiallyas and for the purpose set forth.

2. In a razor or knife Sharpener, the cornbination of a suitable handle,an automatically reversing holder for the razor or knife a framecontrolling the holder and the spring 27 inserted between said frame andhandle and adapted to hold the former centrally in the latter,substantially as described.

3. The combination in a razor or knife Sharpener With the handle 3provided with the longitudinal slot 5 of the holder 17 pivotallysupported Within said handle and provided With the razor holding portionhaving the slot 18, substantially as described.

In testimony whereof I have hereunto set my hand this 24th day ofSeptember, 1888.
